creating geometry out of locators?
 

is there a possibility to create a geometry like a topology out of bout 2000 locators imported from a tracking program?

if yes, I´d be happy!

Hey there.

You could do it, but you may have to write a little script to help you. I've used a similar process (I didn't write the script though, I'm not too hot with Mel). I guess what the script would do is look at all of the locators, and triangulate them all to create the surface, but I'm not 100% sure. Another method that I've used to create a terrain out of Boujou locators is I just created a poly plane that was subdivided a few times, and started snapping points to the locators. I then kept going over the plane subdividing it and snapping points, and finished up using the sculpt poly tool to finish off. I managed to create a really nice, accurate terrain doing this, that tracked perfectly. I don't think that there is a really quick method, it depends on how accurate you need it to be.

well I need it quite precise. got allmost 4000 locators for one shot here. I agree with your method, but its quite a bit of work. concerning the scripting - the locators have chaotic numbers. they´re picked randomly without any system. (besides that I don´t kow mel that good to write a script) guess I have to connect them by hand... argh!!

thx tho for your help!

if anybody of you mel guys and gals are bored and like to help me out you could give me some input how to tackle this problem.


polyCreateFacet -ch on -tx 1 -s 1 -p locator1 -p locator2 -p locator3 ;


this is the basic createPolygon operation. does following thoughts make sense -> ?

to collect all locators position and store it in an array.
select first locator and search for 2 nearest locators.
use 3 locators to create a polygon with above operation.
delete those 3 locators from the array.

hm..

yes that's pretty much how I would do it (however you can delete the locators as they will be used to create more triangles). You can then fix all the normals. Have a look for a MEL triangulation script there must be something out there already.

thx, but I gave it up. mel is still a level to high for me I am recognizing. if there would be more spare time, well. I ended with building it by hand. took me bout 6-7 hours with a horrible geometry. but there´s this wonderful script fitVerts, formerly xyshrinkWrap.

nevertheless thank you!
